Assessment Rationale:

Pholcus dentatus is only known from two sites separated by 25 km in the northern coast of Madeira Island, Portugal. This species is assessed as Data Deficient (DD) due to the lack of knowledge on its distribution, ecology and possible threats. More research is needed in order to assess its extinction risk.

Geographic Range:

Pholcus dentatus is known from only two sites separated by 25 km in the northern coast of Madeira Island (Portugal) between 300 and 450 meters elevation, Fonte da Pedra and Ribeira da Janela (Wunderlich 1995). The species EOO and AOO are unknown.
